vd Claims.

This invention relates to a transload device and more particularly tosuch a device for use in pavement joints, concrete highways, airportrunways and the-like. Such devices are quite commonly used to carry theload between adjacent slabs of concrete, but those transload devices nowin common use have various drawbacks. They may be difficult to assemble,or their cost may be excessive. In some instances, the device is soconstructed that it is difficult or impossible to flow or pack theconcrete solidly around the dowel adjacent the joint.

It is therefore an object of myinvention to provide a transload devicewhich is inexpensive and is easily fabricated by welding the variousparts together.

Another object is to provide such a device made of two units which canbe easily assembled by telescoping the units together.

Still another object is to provide a transload device which enables theconcrete to flow or be packed solidly around the dowel adjacent thejoint. I

These and other objects will be more apparent after referring to thefollowing specification and attached drawings, in which: I

Figure 1 is a perspective view ofan expansion joint assembly;

Figure 2 is a transverse section pansion joint of Figure 1;

Figure 3 is an enlarged sectional view of a detail; 7

Figure 4 is an'elevation of a detail;

Figure 4A is a view taken on the IV-A-IV-A of Figure 4; and

Figure 5 is a view similar to Figure 2, but showing a contraction jointI.

Referring more particularly to the drawings the reference numeral 2indicates a pair of concrete slabs having the usual filler member 4therebetween. My device is made of two complementary units which aretelescoped together. Each unit has two longitudinal rods 8 and 8 spacedfrom the filler 4 and connected by rods ID and I2 which are weldedthereto. Rod I0 is U-shaped with the open end of the U being welded tothe lower wire 6 and the closed part of the U extending above and beingwelded to the top wire 8, thus providing an opening M. A dowel l8extends into the opening l4 and is welded to the rods 8 and Hi. The rodl2 has a vertical portion, the lower end of which is welded to the rod6, and a top portion which forms a clamping device 20. clamping device,as best shown in Figure 4, is

I of the exline The.

provided with a loop 22 for receiving the free end of the dowel l8 and alongitudinal portion 24 which extends along the rod 8. The free end ofthe portion 24 has a hook 26 which is adapted to pass below and extendaround the rod 8 to a point just below the axis of the rod. The rods l0and 12 are arranged alternately with the rods I0 of one unit beingopposite the rods [2 of the other unit. A plate 28 is welded to each ofthe dowels H! on that side of the filler 4 adjacent the rod Ill. Theplates 28 are bent at 30 to receive a longitudinal rod 32 In assembly,the two units are brought to-) gether by passing the free ends of thedowels through the openings 34 into the loops 22. The sleeves 36 andfillers 38 are then applied to the dowels and the hook 26 is moved fromthe dotted line position of Figure 4 to the full line position, thuslocking thetwo units together i with the plates 28 bearing againstopposite sides of the filler 4 to hold it in position while concrete ispoured. The plates 28 do not interfere with the flow or packing of theconcrete around the dowels adjacent the joint, thus making it possibleto provide dense concrete at the most critical places. The devicefunctions in the usual manner as the concrete slabs 2 expand andcontract.

Figure 5 shows my device as applied to a contraction joint. The onlydifference in the two joints are the omission of the sleeves 36 andfiller 38 in the contraction joint and the substitution of a steelseparating plate or filler 40 for the expansible filler 4.

While two embodiments of my invention have been shown and described itwill be apparent that other adaptations and modifications may be madewithout departing from the scope of cluding a pair of telescopingsupporting units, one.

adapted to be positioned on each side of the filler, each unitcomprising a pair of outboard longitudinal rods spaced apart one abovethe other, spaced apart rods extending between and welded to saidlongitudinal rods, said last named rods having a U-shaped upper portionextending above the upper longitudinal rod to form an opening, a dowelpassing through each opening and welded to the walls thereof, a platewelded to each of said dowels and adapted to bear against one side ofsaid filler, each of said plates being bent outwardly below said dowelto provide a longitudinally extending recess therein, an inboard rodwelded to and extending longitudinally between the plates, said lastnamed rod being positioned in said recesses above the bottom of saidplates a substantial distance below the dowel, a clamping rod betweenadjacent pairs of said U-shaped rods extending between and welded to thebottom and top longitudinal rods. each of said clamping rods extendingabove the to longitudinal rod and having a loop receiving a dowel of theopposite unit, each of said clamping rods extending from said loop alongsaid top longitudinal rod and having a hook portion at the free endwhich passes below and around the top longitudinal rod, and a connectionbetween the ends of the inboard longitudinal rod and one of the outboardlongitudinal rods.
